Shin Ei 8TR Fuzz Wah

Can't find much info on a description of it, but what I do know is that it a superfuzz  running into a wah. There's literally 1 component value difference in the superfuzz, the rest is straight up identical to the standard superfuzz.




Quick note about the wiring. Just like the Shin Ei 6TR Fuzz Wah I posted the other day, the fuzz comes before the wah, so you'll wire it up according to the dual effect wiring as shown in the offboard wiring tab. You'll notice instead of making this on 1 massive board I opted for 2 separate boards. This will give you more options for placement in an enclosure, by preventing it from being 1 massive board.

Shin Ei 6TR Fuzz Wah

From Retro-Tone Junkie:

This is a very cool and underrated offering from the king of nasty vintage fuzz. This one is Kent branded but has the shin-ei stamp inside. It is widely known that the wah in these is less than desired. This is definitely not a funk machine and you will not channel your inner Hendrix here, but the fuzz really makes up for it. These are 2 transistors short of being an exact superfuzz circuit (TR-8) and in my opinion lie somewhere between the fy-2 and the fy-6. 

It has 2 knobs for volume and fuzz adjust, as well as a fuzz tone selector switch that changes from hard to soft. Very much like the superfuzz it basically goes from a scooped, darker sounding tone (soft) to a cutting midrange sound (hard). It also has 2 stomp switches, one of which will turn the fuzz on or off. And one that works just like a standard wah would, employed by the treadle.


I got this pedal for (what I would call) a steal, and these (non-superfuzz) versions can be had for very cheap on ebay or the forums. They are well worth it in my opinion, even though this version is known for a severe volume drop and doesn't meet unity gain in most situations (very much like the fy-2) it sounds really great. This is the chainsaw fuzz your friends warned you about, to me its like the superfuzz without the octave up. I'm glad I chose not to follow the hype and took a chance on this one.


This is supposedly the fuzz tone used by Jesus and the Mary Chain back in the day on Psychocandy.

Univox Uni-Comp

Not much info on this one, but basically it was a compressor made by Univox in the 70's as part of their "foot" series. Seems to be loved by many and was recently requested. In addition to the schematic posted in the request section I found another schematic posted over at FSB, so I made 2 different layouts.

One thing to note is that the original didn't use an LED & LDR, but used a Vactrol labeled MCD527. I'm not quite sure what color LED and LDR range you should use. I would start with try a red LED and socket the LDR and try different ones to get a good range. If you were to try a vactrol maybe a NSL32 or VTL5C3 which have bee used on many different optical compressors.

Don't forget if you're using an LED & LDR to cover them in shrink wrap to block out any light and increase their efficiency and effect.

Layout 1: Based on the Schematic in the Request Section


Layout 2: Based on the Trace ad FSB of a Uni-Comp Model CO-105

Lovepedal Hi Volt

"The Hi Volt is a mid- to high-gain dirt box, with a fully saturated effect that is internally charge-pumped to 16VDC, and brandishes a high headroom, custom-tuned 3-band active EQ. This high-voltage configuration allows for very flexible and potent sonic possibilities, ranging from blues to metal and everything in between.
With its generous low-end wallop, the Hi Volt creates amazing depth and three-dimensional mass with an amp or rig of any size. Now your compact combo amp can sound like a towering full stack, simply by engaging the Hi Volt’s unique circuitry.
As you increase the Hi Volt’s “Bass” control, you can add warmth and body to your tone without the signal getting loose or tubby. The Hi Volt is a very tight effect and responds to rapidly changing playing dynamics, just like your favorite tube amp would.
With the gain knob set at around 9 o’clock, you get a tight, British clang that nails your favorite 70’s classic rock riffs. Set the gain at 1 o’clock for more saturation from signing lead tones to 90’s grunge riffage. Setting the gain around 3 o’clock will deliver some of the most brutal tones to ever come out of a stomp box."
